  • The Land and Water Boards of the Mackenzie Valley are responsible for issuing water licences to community governments as required by the Waters Act. However, the responsibility of ensuring and monitoring compliance is shared with the various departments of the Government of the Northwest Territories (GNWT).

    In May 2016, the Boards requested collaboration with the GNWT to improve water licence (WL) compliancy and the effectiveness of the current licencing process.

     In March 2017, the Boards received joint response from the Ministers of the GNWT departments.

  • In December 2011, the Wek’èezhìi Land and Water Board (WLWB) and the Mackenzie Valley Land and Water Board (MVLWB) hosted “An Introduction to Risk Assessment”, which was a 2-day information session on human health and ecological risk assessment. The purpose of the information session was two-fold: to ensure that all parties participating in Board decisions involving risk assessments in the mining industry have a good understanding of the topic, and to promote an open discussion about risk assessment. During the information session, participants heard about how and when to perform a risk assessment,  community involvement in risk assessment, and some case studies of risk assessment in action. The Summary Report provides a description of the key discussion points raised during the two days of the information session.
